well, I didn't like what I was studying at the uni so I'm going to repeat some of the high school exams to enter in a different course
Not sure for u but i live in the us and u can build up from community college and possibly get into better schools by transfer. Im happy where im going tho(tx a&m)
Well, your flair checks out
Can you not repeat your last year and aim for better grades?
I repeated a school year and it didn't give me any disadvantage at all, apart from "losing a year"..
Also don't be too afraid to fail when you are this young. It may take a little bit of time, but you can easily recover..
Lmao dude consider yourself lucky. Go to CC for two years and get some minimum wage job while your at it so you have a source of income. Work hard for those two years, get involved in the community, work on projects, do MOOCs, then transfer to a top university. Don't waste your money on a university for your first two years, the curriculum is all the same for intro classes. Take 2/3 years while in the transfer school to really get all the classes you need and you will be fine.
As for your mindset right now, ask yourself why you want to go to uni. At some point during school you will get stressed out and want to give up/drop out b/c uni ain't easy boi. You will need to find motivation to get through those times and it is important that you really think about this and get serious about it. Honestly you don't look like your mature enough for college, that's ok, I think 90% of college freshman are just going through the system and most will crumble under the pressure of adult responsibilities + schoolwork. Take a gap year or two if you have to to work somewhere, or learn a trade, get a new perspective. School, even uni, is a bubble where you are shielded from how the world really works.
If you know how the world works before you go to college, you figure out why (or why not) college is needed, then you go to college with that mindset and become more prepared than any other student there.
